The issue here: by what means could such velocity be neutralised on impact(over here) if the chute did not deploy. To save the electronic data.Same approach, really, as the Ranger capsule: you need a crushable shock absorber, so the deceleration takes place over tens of centimeters rather than (worst case, hard surface) a few millimeters. Modern electronic gear is pretty tough but there are limits.
Use the FDR/VDR approach separate the storage out and armor it. Use more than one data sink. a ( micro/mini..) SD-Card lanimated between two pieces of "hard"ware should be able to tolerate very high deceleration. The way USB-Sticks are build I would deem them unsuitable for this uwe
